POSITION REVEALING SYSTEM or -Filed April 4. 1919 3 Sheets-Sheet 3 nwmron N HISATTORNEY .valve 53 has a stem 55 Water to the rear of the torpedo Where it is visible.

To control thedischarge of smoke a valve 34, preferably of the butterfly type, is mounted in the passage 33, being fixedly secured to a rotatable spindle which is journalled in and projects from the tube 32 and has its 'exte'iided end supported in a bearing 36 of a standar 37. This spindle 35 has ara-t'het 4O fike't 157 secured "to it in position to be engage" by afspring-pre'sse'd paivl 41 pivoted to a' gear 42, vvhich is t i 'ee to rotate \vith respect to the spindle 35. The ratchet is prerem'biy 'a 'foiir-toothed one inforder to transmit 'a quarter turn to the spindle 35 for each actuation of the gear 42.

a For turning the gear 42 so that the valve 34 iseither openedjor closed, a rack 43 is provided in 'mesh with the gear 42 and formed on the 'prd'e'cting end at a piston rod 44 which passes ivithin -a cylinder 45 ,t'vh'ere it terminates in a piston 46. s'iiitable rigid arm 47 forms 'a gui'de bzearing for the piston rod 44. The piston, 46 is normally maintained at one end of the cylinder 45 by a spring 48 and is arranged to be moved against the spring .piessu'reby fl'u'id "pres'stire admitted b-y wa or, pipe 50 to the end or the cylinder 45 on the opposite [side ef the piston 46 from the spring 48. This pipe 50 communicates ivith a storage tank 51.0511- taining compressed air other suitable pressure for the .piirpose 1 "tended.

For controlling the dmission "or pressure fiuidtothe cyliiider 45, by ivay'of pipe 50', at Will from a distance, a multiple port control valve 52 isinterposed -at a suitable point in the length of the pipe '50 and xvhen in one position establishes communication b'etive'e'n the tank 51 andthe cylinder 45, but in its normal position causes the cylinder to be connectedfto fthe atmosphere and closes the tank portion 6f the pipe Th'e cont'rol valve 52 is, preferably, of the rotary type and is operated by the action of a reciprocal valve 53 through a rack-and ipinio'n means 54, all of. which is fully described in detail in co-pending application Ser. No. f67,947, patented June 6, 1922, Patent No. 1,418,793, for radio system of dirigible control. In view of this the presentdes'cri 'ation vill be limited to an identification of'th'e partsfas a repetition is deemed unnecessary. e

forming thecore of a solenoid, 56 which is arrange'd tobe energized by the closing "of acir cuit :57 inclnding a battery60, a terminal 161 and an armature switch 62, this lattergbeihg normally held by a spring 63 to break the eirciiitf57= A "stationary electro inagnet 64 islocated in operative'relation to the armature "62 midis arranged to be energized by a closed oscillatory circuit including a conductor '65, a

detector 66, condensers 67 and a secondary inductance 0011 70, yvhich isiiiductively connected to a primary maueranee eon 71 0f an open aerial circuit 72 arrangec' to respond to radiant energy. Thus when an impulse is received by the aerial *circuit 7 2 the electro-magnet 64 will be energized and thereby close the circuit 57 to cause the solenoid 56 to actuate the valve 53 and admit pressure fluid to shift the ratchet mechanism 54 and position the rotary control valve 52 correctly to cause pressure fiuidto pass Way of pipe 50 to the cylinder 45. This action tal'zes place, preferably, through the sending of a long impulse, thus allowing the rotary valve 52 to be adjusted for other operative positions by a short impulse or a succession of short impulses. While the toieg'oing is described as the preferred construction it should be understood that there are many Ways in which the opening and closing of the pipe 50 to fluid pressure may be accenplished and the invention is not limited to the form here described.

In the operation or this for'fnei the invention an impulse of the proper eharacter' received With the parts in the position shown in "Fig, 1, will cause the pressure fluid to enter the cylinder 45, thereby movihg the piston 46 ahd causing "the reel; 43 to turn the gear 42 fso that the pawl 41 rotates the ratchet Othrough a quarre'ref a revolution. The spindle 35 is correspondingly turnedand the valve 34 thereupon closed. A'nother impulse is then sent to exhaust tl'i'e cylinder 45 and "estore the parts to normal position, but the valve is left in cl'o'sed posi'ti'on. To open the valve 34 again to release the sinoke to give an indication of the position of the torpedo, an impulse issent, as above described, and the ratchet -4O 'is'a'g ai'n given a quarter turn thereby opening the valve 34. The valve 34 desired manner, being left open to emit a continuous smoke trail, or intermittently operated tocause a succession "of sinekepuffs tobe emitted.

In the frm of the invention shoi'vn in Fig. 3, the firebox 12 contains a chemical 73 requiringair to support combustion andgive pif a 'denjse'sinoke,an'd to this end tvvo tiibe's 74 and 7 5, leading respectively from olifierent parts of the fireboX 12, are 'ro'vided to establish communication With ft 1e exhaust :pipe 11 and permit air to circulate through the firebox 12 in c 0ntac t with the chemical 73. The spindle 35, in this instance, carries "t o yalv'es 76 and 77, one located in the tube 74 and the other in the tube 75, both being controlled t2) ennui ahebu sl y b'peh 'or "close 'tjli'e, t\'vo passages between the firebox '12 and the -eithaust pipe 11. The distant migra ed the peruse-en firing means are preferably the same as shown in-cbn'nectitn with the fofrm of Fig. 1.
